Sure there were Americans involved, but it was arguably a worldwide operation. Plenty of ties to the UK, EU, Russia, Israel and various middle eastern countries. I’m happy to talk crap about America (amongst other countries) but I prefer to stick to facts when doing so.

We also need to consider the media bias though. Most outlets I have seen that are reporting on the files are US based. They will likely recognize well known US names easily and so will their audience. It’s logical to report on those first.
Also just to add more names to the non-US pile:
Willing to bet there’s countless more high ranking politicians and royals worldwide involved. We’ll get more names in time I am sure.
